Abstract:

In this paper, we use the Thue-Morse sequence and the paperfolding sequence to build a Dirichlet series that evaluates to a linear combination of the Riemann zeta function at odd positive integers and odd powers of π. In doing so, we also provide an alternative proof of a 2015 result by Allouche and Sondow.
